Muczne [ˈmut͡ʂnɛ] is a village in southeastern Poland in Subcarpathian Voivodeship, Bieszczady County, Gmina Lutowiska, near the border with Ukraine, in the valley of the Muczny stream.

In 1944, troops of Ukrainian Insurgent Army raided the village and murdered 70 people of Polish nationality in the Muczne massacre.

In the 1970s, Muczne was a secluded place where Polish Communist leaders could come to relax and often spend time and host their international VIPs.

The former PM of Poland, Piotr Jaroszewicz, is said to have hunted a bear that is displayed in the Bieszczady National Park Museum.

For several years, Muczne was called Kazimierzowo to honor colonel Kazimierz Doskoczyński who was the head of another state estate in Arłamów.
